Embodiment 1

[0054] 1. Synthesis of bis(4-benzoyl)aniline

[0055] Take 15.5mL of anhydrous DMF ice-water bath to below 0°C, add 15.5mL of phosphorus oxychloride dropwise, stir at room temperature for 40min, add 2.0g of triphenylamine and heat the mixture to 95°C and stir for 14 hours. After the reaction was completed, the reactant was cooled to room temperature, poured into ice water, then adjusted to neutrality with sodium hydroxide, stirred at room temperature for 2 hours, extracted with dichloromethane, dried over anhydrous magnesium sulfate, concentrated and separated by silica gel column chromatography A white powder was obtained, yield: 90%.

[0056] 1 H-NMR (DMSO, 400MHz) δ(ppm): 9.87(s, 2H), 7.84(d, 4H), 7.47(t, 2H), 7.31(s, 1H), 7.21(d, 2H), 7.16( d, 4H).

[0057] 2. Synthesis of compound 1

[0058] 1 mmol of bis(4-benzoyl)aniline and 2 mmol of 4-trifluoromethylbenzohydrazide were added to the flask, followed by 6 ml of ethanol and 1 to 2 drops of glacial acetic acid. The re...

Description

technical field [0001] The present invention relates to the technical field of aggregation-induced luminescence materials, in particular to a compound with aggregation-induced luminescence and mechanochromic properties, a preparation method and application thereof. Background technique [0002] The phenomenon of Aggregation Induce Emission (AIE) was proposed by Tang Benzhong's research group in 2001. It is well known that traditional fluorescent materials usually emit strong light in solution, but very weak or even no light in solid state or aggregated state. This aggregation-induced luminescence quenching phenomenon greatly limits the use of fluorescent materials. However, the luminescence of AIE materials is weak in solution, and the luminescence is significantly enhanced in aggregated or solid state. This AIE-type material can be widely used in many aspects, especially in solar cells, OLEDs, biosensors, and multiple stimuli-responsive materials. [0003] When some mater...
